CARE AND MAINTENANCE
Important Information on Battery Chargers
Using your inverter with battery chargers for power tools, flashlights,
video cameras and laptop computers may cause damage to the
inverter or the charging unit. Check with the appliance manufacturer
for compatibility with modified sine wave inverters if you're unsure.
Although we advise against it, if you attempt to use a charging unit,
monitor the temperature of the charging unit for approximately 10
minutes. If the charging unit becomes unusually warm, disconnect it
from the inverter immediately.
